Problems with cpp (in wxWidgets-devel)

[Mojca Miklavec]

Hello,

if I try to build wxWidgets with a patch that enables building with
clang. But if I try to build +universal, it seems that I hit the
problem of "looks like it's using parts of QuickDraw that are gone in
Lion", so I need to build with SDK for 10.6.

But then it fails with an equivalent of
    > touch a.c
    > cpp -isysroot /Developer/SDKs/MacOSX10.6.sdk a.c
    i686-apple-darwin11-llvm-gcc-4.2: c: No such file or directory
(replacing with /Applications/Xcode.app/.../MacOSX10.6.sdk doesn't
solve anything; a.c has some contents, but it doesn't make any
difference to cpp either)

My question is: does that work for others? I had Xcode 4.2 installed
and installed 4.3 on top. Is only my system that is messed up or is
there something else that I'm missing? The file /usr/bin/cpp is a
shell script.

Thank you,
    Mojca
